筆記本(ben)電(dian)池(chi)(chi)充(chong)電(dian)時(shi)間(jian)(jian)注意(yi)，到底筆記本(ben)要(yao)充(chong)電(dian)多(duo)少時(shi)間(jian)(jian)才是正(zheng)確的(de)(de)，在充(chong)電(dian)過程只能夠(gou)要(yao)把握什(shen)么？時(shi)間(jian)(jian)多(duo)少是否(fou)會影響筆記本(ben)電(dian)池(chi)(chi)的(de)(de)使用壽命呢(ni)？下面就這些問(wen)題(ti)擴展開，看(kan)看(kan)對于(yu)筆記本(ben)中(zhong)最(zui)脆(cui)弱的(de)(de)筆記本(ben)有(you)什(shen)么可以(yi)注意(yi)的(de)(de)地方(fang)。

筆記本電池充電時間

謠傳一：新電(dian)池的(de)激活

新電池應該(gai)用循(xun)環(huan)充放電的(de)(de)方式(shi)來激活電池的(de)(de)性能(neng)。

真相：準(zhun)確地說(shuo)上(shang)述說(shuo)法并不是(shi)謠傳。因為有的(de)(de)筆記本電(dian)(dian)(dian)(dian)池(chi)從(cong)生產以后(hou)到(dao)客戶的(de)(de)手里(li)會有一(yi)(yi)定的(de)(de)時(shi)(shi)間差，短(duan)則一(yi)(yi)個月，多則半年。對于時(shi)(shi)間差較長的(de)(de)電(dian)(dian)(dian)(dian)池(chi)，其電(dian)(dian)(dian)(dian)極材料會鈍化，因此廠商建議初次使(shi)用的(de)(de)電(dian)(dian)(dian)(dian)池(chi)最(zui)好進行3~5次完全充(chong)(chong)放(fang)電(dian)(dian)(dian)(dian)過程，以便(bian)消除電(dian)(dian)(dian)(dian)極材料的(de)(de)鈍化，達到(dao)最(zui)大(da)容量。但(dan)一(yi)(yi)般的(de)(de)這里(li)的(de)(de)充(chong)(chong)放(fang)電(dian)(dian)(dian)(dian)不是(shi)深度放(fang)電(dian)(dian)(dian)(dian)，而是(shi)淺放(fang)電(dian)(dian)(dian)(dian)，這里(li)就有一(yi)(yi)個筆記本電(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)時(shi)(shi)間的(de)(de)把握(wo)問(wen)題了。

筆(bi)記本電(dian)池“前三(san)次(ci)”充電(dian)

謠傳(chuan)二：當一(yi)(yi)款(kuan)新(xin)的電池(chi)(chi)買(mai)回來以后(hou)，一(yi)(yi)般會說最好進行(xing)三次循環充(chong)放電，而筆記本(ben)電池(chi)(chi)充(chong)電放電時(shi)間應該超過12小(xiao)時(shi)，以便激活電池(chi)(chi)最大(da)效能。

真相：鎳氫電池為了達到最完美的飽和狀態，需要經過“補充”和“涓流”過程，這個時間一般在5小時左右。而目前鋰離子電池的“恒(heng)流”、“恒(heng)壓”充電(dian)特性更(geng)是(shi)將(jiang)其(qi)深充電(dian)時間控(kong)制在4小(xiao)時以內。一旦(dan)充滿，電(dian)池內部(bu)的保護電(dian)路便會(hui)自動停(ting)止(zhi)充電(dian)，因(yin)此這種做法是(shi)不(bu)科學也沒有實(shi)際(ji)意(yi)義的。

有人曾(ceng)用手(shou)(shou)機(ji)做過試驗(yan)。在用旅(lv)充(chong)(chong)(chong)(chong)(chong)(chong)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)將電(dian)(dian)(dian)池(chi)充(chong)(chong)(chong)(chong)(chong)(chong)滿后，轉(zhuan)用座(zuo)充(chong)(chong)(chong)(chong)(chong)(chong)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)來確認(ren)(ren)電(dian)(dian)(dian)池(chi)的飽和程度。當他發(fa)現座(zuo)充(chong)(chong)(chong)(chong)(chong)(chong)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)仍(reng)(reng)然對電(dian)(dian)(dian)池(chi)進行充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)時(shi)，便認(ren)(ren)為(wei)(wei)電(dian)(dian)(dian)池(chi)仍(reng)(reng)未達(da)到(dao)飽和狀態(tai)。其實這個(ge)測試方法欠(qian)缺(que)嚴謹。原因在于，座(zuo)充(chong)(chong)(chong)(chong)(chong)(chong)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)的指示燈并不是(shi)檢測真正飽和與(yu)否(fou)的惟一(yi)標(biao)準，座(zuo)充(chong)(chong)(chong)(chong)(chong)(chong)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)的基準電(dian)(dian)(dian)壓不一(yi)定等于手(shou)(shou)機(ji)的基準電(dian)(dian)(dian)壓，因此當手(shou)(shou)機(ji)認(ren)(ren)為(wei)(wei)電(dian)(dian)(dian)池(chi)達(da)到(dao)飽和狀態(tai)時(shi)，座(zuo)充(chong)(chong)(chong)(chong)(chong)(chong)充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)器(qi)(qi)也許并不這么認(ren)(ren)為(wei)(wei)，依然進行充(chong)(chong)(chong)(chong)(chong)(chong)電(dian)(dian)(dian)，但(dan)是(shi)否(fou)充(chong)(chong)(chong)(chong)(chong)(chong)進去(qu)，就只有它(ta)自己知道了(le)。

只要筆記本(ben)電(dian)(dian)池充電(dian)(dian)時間放(fang)電(dian)(dian)時間把握得當，則(ze)有可能會達到最佳狀態(tai)

謠傳三(san)：只(zhi)要(yao)充(chong)電電池使用(yong)得當，就會在(zai)某一(yi)段循環范圍內出現最(zui)佳(jia)狀(zhuang)態，達到(dao)最(zui)大容量(liang)。

例如(ru)早期的鎳(nie)(nie)氫、鎳(nie)(nie)鎘電池，如(ru)果使用得當，定(ding)期維護，會在15~203個循環點中達到其(qi)容量(liang)的最大值（出廠容量(liang)為1200mAh的鎳(nie)(nie)氫電池在循環120次后，容量(liang)有可能達到1200mAh）。

真(zhen)相：這(zhe)種說法(fa)在日系產(chan)品電(dian)池(chi)中(zhong)比較常(chang)見，在其技術規(gui)格書中(zhong)的(de)循(xun)環(huan)(huan)特性圖中(zhong)通(tong)常(chang)可以(yi)看到。然(ran)而對目(mu)前主流(liu)的(de)鋰離子電(dian)池(chi)而言(yan)，這(zhe)種循(xun)環(huan)(huan)的(de)峰值現(xian)(xian)象(xiang)是(shi)不存在的(de)。因為鋰離子電(dian)池(chi)從出廠到報(bao)廢，其容(rong)量的(de)表(biao)現(xian)(xian)為循(xun)環(huan)(huan)一(yi)次少一(yi)次，從未出現(xian)(xian)過(guo)容(rong)量回升的(de)現(xian)(xian)象(xiang)。也許有(you)朋友會問(wen)，某(mou)些ThinkPad筆(bi)記本(ben)用戶通(tong)過(guo)深(shen)放電(dian)，可以(yi)恢復電(dian)池(chi)的(de)容(rong)量。實際上(shang)那只(zhi)是(shi)測試軟件(jian)的(de)錯誤檢(jian)測而已，電(dian)池(chi)的(de)實際容(rong)量根本(ben)沒有(you)提高。

筆記本電池(chi)使用時間正確的(de)(de)影響(xiang)的(de)(de)因素是(shi)筆記本電池(chi)所處的(de)(de)環境(jing)的(de)(de)溫(wen)度，當然筆記本充電時間也有一定的(de)(de)關系，不過還是(shi)次于環境(jing)的(de)(de)影響(xiang)。

鋰離子電池到底有沒有最佳狀態？答案是肯定的，這跟其所受環境溫度的變化有關。一般情況下，鋰離子電池在26℃~41℃的(de)環境(jing)下會表(biao)現出極好的(de)性(xing)(xing)能。而(er)到了(le)低溫或高(gao)溫狀(zhuang)態，其(qi)性(xing)(xing)能就要大打折扣(kou)了(le)。例如(ru)你在室外陽光直(zhi)照的(de)情況下使用筆記本電(dian)腦，就沒有(you)在室內使用的(de)時間長。

謠傳(chuan)四：兩個標(biao)稱容(rong)(rong)量相同（例如(ru)800mAh）的(de)電池來說，如(ru)果(guo)一(yi)個實際測得容(rong)(rong)量為860mAh，另一(yi)個為805mAh，那么860mAH的(de)就一(yi)定(ding)比805mAh的(de)好。

真相：一(yi)般而言(yan)，不(bu)同型(xing)號（不(bu)同體積）的(de)(de)鋰離子電(dian)(dian)(dian)池(chi)(chi)(chi)，容(rong)量(liang)(liang)(liang)(liang)(liang)越高(gao)(gao)(gao)使用(yong)的(de)(de)時(shi)間(jian)也就越長。如(ru)果拋開體積和(he)重量(liang)(liang)(liang)(liang)(liang)等因素，當然是容(rong)量(liang)(liang)(liang)(liang)(liang)越高(gao)(gao)(gao)越好。但對于(yu)兩(liang)個(ge)標稱容(rong)量(liang)(liang)(liang)(liang)(liang)相同（例(li)如(ru)上(shang)例(li)）的(de)(de)電(dian)(dian)(dian)池(chi)(chi)(chi)卻(que)未必。因為實際(ji)容(rong)量(liang)(liang)(liang)(liang)(liang)高(gao)(gao)(gao)的(de)(de)那(nei)個(ge)電(dian)(dian)(dian)池(chi)(chi)(chi)，很可能(neng)在(zai)電(dian)(dian)(dian)極材(cai)料(liao)中(zhong)添加(jia)了用(yong)于(yu)增加(jia)初始容(rong)量(liang)(liang)(liang)(liang)(liang)的(de)(de)物質，減少了用(yong)于(yu)穩(wen)定電(dian)(dian)(dian)極的(de)(de)物質。其結果就表(biao)現(xian)在(zai)循(xun)環了幾十次之后，容(rong)量(liang)(liang)(liang)(liang)(liang)高(gao)(gao)(gao)的(de)(de)那(nei)塊迅速衰減，而容(rong)量(liang)(liang)(liang)(liang)(liang)低的(de)(de)卻(que)依(yi)然堅挺。國內許(xu)多廠(chang)商為了縮(suo)減成本，擴(kuo)大銷(xiao)量(liang)(liang)(liang)(liang)(liang)，往往就采用(yong)了這(zhe)種手段來生(sheng)產高(gao)(gao)(gao)容(rong)量(liang)(liang)(liang)(liang)(liang)電(dian)(dian)(dian)池(chi)(chi)(chi)。用(yong)戶在(zai)使用(yong)半年后就會(hui)發現(xian)工(gong)作時(shi)間(jian)大為縮(suo)短。總之，提高(gao)(gao)(gao)容(rong)量(liang)(liang)(liang)(liang)(liang)的(de)(de)代價就是犧牲循(xun)環壽命，廠(chang)商不(bu)在(zai)電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)材(cai)料(liao)上(shang)下文(wen)章，是不(bu)可能(neng)真正(zheng)提高(gao)(gao)(gao)電(dian)(dian)(dian)池(chi)(chi)(chi)容(rong)量(liang)(liang)(liang)(liang)(liang)

電池的保存

謠傳(chuan)五(wu)：充電(dian)(dian)電(dian)(dian)池如果不(bu)使(shi)用，應該放光了(le)電(dian)(dian)再保存。

真(zhen)相：其實不僅僅有上面提到的(de)謠傳，鋰離子電池(chi)(chi)到底該(gai)充(chong)滿(man)了(le)(le)保(bao)存還(huan)是(shi)(shi)(shi)放光了(le)(le)保(bao)存肯定會讓很多人感到迷惑？這一(yi)問題的(de)解答要從其先(xian)天性的(de)缺(que)陷談起，那(nei)就是(shi)(shi)(shi)“老化效應”。鋰離子電池(chi)(chi)在存儲(chu)一(yi)段(duan)時間后(hou)，即(ji)使不進行循(xun)環使用，其部分容量也會永(yong)久性的(de)喪失，這是(shi)(shi)(shi)因為鋰離子電池(chi)(chi)的(de)正負(fu)極材料自出廠時便開始了(le)(le)它們(men)的(de)衰(shuai)竭(jie)歷程(cheng)。不同的(de)溫度及(ji)飽和(he)程(cheng)度下(xia)老化的(de)幅度也是(shi)(shi)(shi)不同的(de)，具體(ti)幅度可見表所示。

由此可見，存儲溫度越高、電池充的越滿，容量的幅度就越大。因此對于鋰離子電池的長(chang)期(qi)保(bao)存(cun)(cun)，用戶應當將其(qi)(qi)電量(liang)控制在40%，并存(cun)(cun)儲(chu)在15℃甚至更低的溫度下即(ji)可。至于那些鎳氫和鎳鎘電池則(ze)不存(cun)(cun)在這一“老化(hua)效應”，長(chang)期(qi)儲(chu)存(cun)(cun)后只需進行幾次完(wan)全充(chong)放電即(ji)可恢(hui)復(fu)其(qi)(qi)原始容量(liang)充(chong)滿電后續充(chong)

謠傳六：筆記本電(dian)池充電(dian)時間一般是有控制的(de)，對于筆記本電(dian)池充電(dian)充滿以后，在(zai)繼續(xu)對電(dian)池充電(dian)充1～2小時，這(zhe)樣做(zuo)有利于增強電(dian)池的(de)飽和度(du)。

   其(qi)實(shi)現在的筆記本(ben)而電池一般都有筆記本(ben)過電保護電路，充滿點以(yi)(yi)后他(ta)會自動(dong)切斷充電電路。所以(yi)(yi)充電時間是(shi)(shi)固定的，滿了以(yi)(yi)后電源只對筆記本(ben)設(she)備進行供電，即(ji)時電池再充12個(ge)小(xiao)時也是(shi)(shi)沒(mei)有用處(chu)的。
